A better way to choose your sneaker size

A desk review based on available product information. Individual fit and performance vary.

Size labels are useful references, but they are not a universal fit guarantee. Two shoes carrying the same EU or US number can feel different because of their shape and construction. For a remote purchase, the goal is to give the seller clear information and obtain a model-specific recommendation you can keep with your order.

Measure both feet

Stand on a flat surface in the socks you expect to wear. Measure each foot from the back of the heel to the longest toe, and record the widest part of the forefoot. Repeat the measurement rather than relying on one mark. Keep the dimensions in millimetres and note any difference between the two feet.

Read the chart heading

Check whether the number describes foot length, a size designation or an internal shoe measurement. These are not interchangeable. Do not add an arbitrary allowance and then use a chart that already accounts for fit. Ask the seller what the chart means if its headings are unclear.

Identify the exact shoe

Send the brand, model, product code and version along with your measurements. A familiar brand name is not enough: different lines can use different shapes. Include a previous shoe that fits you well as additional context, but do not treat that example as an automatic conversion rule.

Discuss width and how you will use it

Mention a broad forefoot, a narrow heel or preferred socks in the inquiry. A longer size is not always an effective answer to insufficient width. If you use your own insoles, explain this before ordering and ask whether the original insole can be removed; do not assume it is removable.

Protect the decision

Request the recommended labelled size and any unresolved uncertainty in writing. Check which try-on conditions preserve an exchange, who pays return shipping and whether another size is actually available. On arrival, compare the box label and shoe label with the quotation before extended use. A careful size process reduces ambiguity, but it cannot make an untried model fit every foot.
